Amazon just opened a cashier-free supermarket

Amazon Go is a new kind of store with no checkout required. We created the worldis most advanced shopping technology so you never have to wait in line. With our Just Walk Out Shopping experience, simply use the Amazon Go app to enter the store, take the products you want, and go! No lines, no checkout. (No, seriously.)Our checkout-free shopping experience is made possible by the same types of technologies used in self-driving cars: computer vision, sensor fusion, and deep learning. Our Just Walk Out technology automatically detects when products are taken from or returned to the shelves and keeps track of them in a virtual cart. When you're done shopping, you can just leave the store. Shortly after, we'll charge your Amazon account and send you a receipt.I find this absolutely fascinating and immensely desirable.I live in a small rural town in the middle of nowhere, and only very recently did we finally get a brand new supermarket with the latest self-checkout and contactless payment technologies (voted most beautiful supermarket in the country, I might add, and a 73-year old family business - we're proud of our own), and it's just so much more convenient than old-fashioned cash registers. I know a number of people prefer being served by a cashier, but honestly - to me it's just wasted time I could spend on something useful.In any event, the idea of just taking stuff off the shelves, without even having to scan them or pay for them at a terminal seems like the next logical step. I don't like the idea of online grocery shopping (I want to see how fresh my produce is before buying it), so this is an excellent compromise.
